Abstract: The reaction of different substituted [alpha] -cyanooxiranes with thiourea resulted in the formation of the 2-aminothiazolinone derivative 2-amino-5-(2,5-dimethoxyphenyl)-1,3-thiazol-4(5H)-one, C₁₁H₁₂N₂O₃S, (I), and the 2-aminothiazole derivative ethyl 2-amino-5-(2,5-dimethoxyphenyl)-1,3-thiazole-4-carboxylate, C₁₄H₁₆N₂O₄S, (II). The geometries of the two crystallographically independent molecules in (II) are nearly identical but mirror related. The crystal structures of both compounds contain two types of intermolecular hydrogen bonds.

Formula: C₁₁H₁₂N₂O₃S and C₁₄H₁₆N₂O₄S
